Norwich City boss Chris Hughton says they're working 24-7 in this summer's transfer market.

Club captain Grant Holt has been linked with a move to Premier League newcomers Crystal Palace, while the Canaries are also said to be tracking Sweden international Ola Toivonen at PSV Eindhoven.

Hughton, however, refused to be drawn on any transfer specifics.

"We are working very hard behind the scenes," he said.

"We are a club which wants to make progress, that means any areas of the squad we can improve, we will do."
